Fuel Lines

[Nova_Tek]

So after spending many hours on the Cavalier today, changing oil, filter, lubricating cylinders & cams etc etc I finally got to turn it over and it started (after a good 30 secs of cranking on the 2nd attempt), but it ran but very rough. Weirdly, giving it some throttle made it drop revs while it idled better off throttle.

I noticed a hissing and found it peeing fuel from the fuel line Took a photo of the offending hose (luckily it's not the metal pipes!)

Unfortunately, I didn't have my axle stands with me so couldn't safely spend time underneath to remove and measure. From what I remember these two hoses are 10mm & 7mm ID, but can anyone confirm?

Thanks

If it is a rubber hose, it should be 7.8mm bore (internal diameter).

It is that size to fit snug over 8mm metal diameter pipework.

Thanks for the reply Robsey,

I've just attached the photo link.

Are they both 7mm or is one larger than the other?

[Robsey]

They should be the same bore.

Maybe one has been replaced previously.
Outer diameter should be about 13mm.

Cheers Robsey,

Great, if they are that size then I have a length of that hose already. They'll be removed today and replaced.

If that hose is cracked / split, have a look at the rest of the hoses on the car.
It is likely that other hoses may be cracking or splitting too.

The hoses in the engine bay were recently replaced as they were leaking too. The metal pipes don't look too great though... Will need to be replaced soon.
